The thyroid gland, located in the front of the neck, just below the Adam's apple, takes in iodine from the diet and produces thyroid hormone. Thyroid hormones affect a person's physical energy, temperature, weight, and mood. Diseases of the thyroid gland are usually associated with the production of the thyroid gland. too little thyroid hormone (hypothyroidism) or too much thyroid hormone (hyperthyroidism).
Because undiagnosed thyroid conditions can increase your risk of developing certain other conditions, it is important to have a family history of thyroid disease and to watch for any unusual symptoms you have.

The most common cause of the thyroid failure are autoimmune diseases. It's when your immune system mistakenly attacks your thyroid, a gland that produces hormones that control a wide variety of body systems and functions. The two most common types of autoimmune thyroid disease are Hashimoto's thyroiditis, which causes too few hormones to be produced, and Graves' disease, which causes overproduction of hormones.

Screening for thyroid disease is similar to other medical examinations. The doctor will look at the patient's medical history, examine the thyroid gland, and may order blood tests or other diagnostic tests to check Thyroid function.
There are three standard blood tests for thyroid function: thyroid hormone, usually T3, T4, and thyrotropin (TSH) measurement. TSH is a hormone produced by the pituitary gland that controls the amount of thyroid hormone produced by the thyroid gland. Blood tests often reveal problems with thyroid function.
Hypothyroidism generally requires only thyroid hormone replacement by taking a single tablet daily at a dose adjusted to achieve normal thyroid hormone levels. Autoimmune thyroiditis is a condition that can cause hypothyroidism. It usually doesn't cause symptoms that require treatment unless hypothyroidism develops. In some cases, thyroid hormone replacement is required. Treatment for hyperthyroidism may include thyroid medication, radioactive iodine131, or, in rare cases, thyroid surgery.
Measuring thyroid antibodies can help diagnose autoimmune thyroid diseases such as Graves' disease, the most common cause of hyperthyroidism, and Hashimoto's disease, the most common cause of hypothyroidism. Thyroid antibodies are produced when the immune system mistakenly attacks the thyroid gland. Your doctor may suggest a thyroid antibody test if other blood tests indicate a thyroid disorder.
